The present invention concerns synchronization of correlated media presentations among two or more media devices. Each device makes a determination as to whether inter-presentation synchronization may be outside of a predetermined tolerance. If so, the device making the determination communicates its buffer and playback status to the other device. Based upon comparison of the buffer and playback status of the local presentation with the buffer and playback status of the presentation at the other device, each device makes a determination as to whether to pause play-back, so as to allow the other device to catch up, advance playback, so as to catch up with the other device, or take no action, allowing the other device to take action to correct the synchronization issue. |
